Docomo Genuine Earphone Microphone

This is an earphone with a microphone specifically for Docomo's FOMA mobile phones.

I purchased it at a Docomo shop several years ago.
I didn't use it much, only when talking in the car, so it's not heavily used. I haven't used it since switching to a smartphone recently, but it was working without any issues.
I will disinfect it as much as possible before shipping.
